RAILWAY SWITCH Np ono'slsme. FROG.

citizen of the'United States, residing at Arcola, in the y'county ofDouglas and State of Illinois, have invented certain new and usefulImprovements in Railway Switch' and CrossingFrogs, of which thefollowing is a specification. A

My invention relates to the joints or crossovers of railway rails, landparticularly tothe @means for safely guiding the wheelon the tions takenthrough the rails respectively rails .at the frog points. The objects ofthe invention are, to provide a guard to engage the tread rim of thewheel while the tread runs on the rail as is customary; to provide vguards which will prevent the jumpin of the rail loose or broken wheelsor roken iianges, increasingsafety in railway-crossings to providemaximum support for the tread of the wheels along 4the entire distanceof the frogs; to providea guardy for the wheel upon both sides, and togenerally improve the construction .and operation of railway frogs.Thescbiects and other advantages to hereinafter appear, I attain bymeans of the construction illustrated in 'a preferred form as 4 appliedto an acute-angle crossing, in the accompanying drawing, wherein Figure11s a plan view of the crossing, and Figures 2, 3, and' 4, are verticalcross secilong the lines (2) (3), and (4) of Figure 1. AIn the presentpractice in railway crossings it has been customary to rovide a guard`engaging the flange. of the w eel on the opposite side of the trackfrom the frog, to pull the wheel over. vI find it much safer to providea guard to enga e the rim of the tread of the wheel itself, an thusavoid the danger from sprung axles or loose wheels, the Wheel beingitself directly guarded when it comesto the point of the crossing. Theinvention is applicable to all kinds of crossing points, whether theyare rigid, spring-rail, or any street railway crossing, and it is ofcourse applicable to any acute-anffle'frog or crossing.

In the' drawing it will e'flseen that the ordinary rails 5 .and 6 areshown coming to a point and spliced at 7, as is customary. l The(zo-operating portions of the rails, 8 and 9 ref spectively, areprovided with a bend as shown, and-project forward in the parts 11 so asto run parallel with the point 7 on the two opposite sides, leaving roomfor the flange of the wheel, very much asis customary in suchdevices.For the guard rail, I use the Speccationvof Letters Patent.

than the rails 8, 9, and it runs parallel with the right hand portion ofthe frog, up past the point 7. From this point out, tliebottom flange ofthe rail 12 isY out olf,'as will be clearfrom Figure 3, and it isspliced-:and bolted to the web of the rail 8, which is also cut andcontinued beyond the oint 7 only in its web and flange, the head o therail being cut off as will be clear from said figure. That'is, the rails8 ,and 12 yrespectively are s liced together so that beyond the point 7the head of the rail 12 is supported by the flange and web of the rail8. yThe head of the rail 11 and part of the head of the rail 12 lie sideby side for a certain distance as lvshown in Figure 3 and thus a supportfor the tread of the wheel is provided all the wa until the wheel comesupon the point 7 of he spliced rails 5 and 6. The flange 13 of rail 12being removed to allow of-the head 14 .being supported upon the web andflange 10 of the rail 8. Usual fillerblocks 15 are used to connect andstiffen the-device and they are preferably bolted together with bothside rail webs by means of bolts 16, or fastened toa bottoni late bymeans of ,rivets or a combination of both. The ends'of the guide rails12 are al both ends planed off with a slant as shown at 17.

By this construction it will be seen that when the wheel comes in asindicated in Figi ure 1, moving toward the frog point, the rim of thewheel will be en aged directly by the guardY rail 12, and a ter passingthe point marked by the line (4), both' the tread and the flange of theWheel will bebonfined, and the tread is supported all along engaging thepoint 7 before it leaves the topjof the rail surface' l1, andcontinually keeping the side of the rim against the guard rail 12 untilthe flange has entirely come upon jhe rails 5 and 6 at the point 7 inthe regular order. As the wheel does not depend at all oii the flan e ofits mate to pull it over or hold; it in p ace, the Wheel is positivelyand firmliy7 confined to its position and safety supported throughoutthe crossing. Other advantages of the device will readilyoccui to inosefamiliar with the art.

Having thus described my invention an illustrated its use, what I claimas new, and

high rail 12, having a wider web and higher desire to secure by LettersPatent, is thefollowing:
